Two unbiased dice are thrown once. Write all the possible outcomes of this experiment. What is the probability that the sum of numbers on two dice is smaller than $5$?

$A$ game of chance consists of spinning an arrow which comes to rest pointing at one of the numbers $1, 2, 3, \dots, 11, 12$ on a circular disc. All these outcomes are equally likely. Then, the probability that the arrow rests to point at $7$ is ..........

Two dice are thrown at the same time and the product of numbers appearing on them is noted. Find the probability that the product is less than $9$.

Two dice are thrown simultaneously. What is the probability that the sum of the numbers appearing on the dice is
$(i)$ $7 ?$
$(ii)$ a prime number?
$(iii)$ $1 ?$

If $P(A) = 0.54$,then $P(\overline{A}) = \ldots$

When a balanced die is rolled,the probability of getting a multiple of $3$ on it is $\ldots \ldots \ldots .$
